So mine at least are limited to a total length of approx .750".
Someone with a different backspacing may have deeper holes, but I believe Vintage only supplies 1 style of nut regardless. I am unaware if they have changed to a non-tapered ( flat bottom) style of nut.

Thanks Craig
Craig,

Do you have a special back-spacing on your rims? Can you measure your back spacing? Thanks!

David
